ATTACHMENT FOR THE FILLING MOTIONS OF LOOMS.

SPECIFICATION forming part of Letters Patent No. 470,253, dated March 8,1892.

Application filed September 19, 1891. Serial No. 406,180. (No model.)

To all whom it may concern.-

Be it known that I, WVILLIAM OBRIEN, of Taunton, in the county ofBristol and State of Massachusetts, have invented a new and usefulAttachment for the Filling Motions of Looms, of which the following is aspecification.

This is an attachment or device made integral with and comprising theweft-grate and applied to the lathe so that it lies within the crease,practically filling it, the object being to effectually prevent thethread or filling from falling into said crease or getting under the endof the fork. The device prevents the filling from catching under thefork, thus doing away with dirty selvages and giving the fork a betterand more uniform lift; hence allowing the loom to run when it wouldotherwise stop. The fork need not be filed to cause it to lift, but willlift as well or better if it is perfectly smooth.

In the accompanying drawings, in which similarletters of referenceindicate like parts, Figure l is a plan View of a portion of a loom withmy attachment applied. Fig. 2 is a section on line 00, Fig.1. Fig. 3 isan enlarged perspective showing the attachment in position.

In the drawings, A represents a portion of the frame.

B is the beam.

0 is a cam operating the fork-leverD,whi cl1 operates the weft-fork E inthe box H, of which 11 is the sliding portion pushing the lever I,pivoted to the extension J on the frame J.

K is the shipping-lever, bifurcated at one end and straddling andoperating the beltshipper K, the lever K being pivotally secured at itsother end to the shipper L, which ships the belt L from the fast. to theloose pulley, and vice versa.

M is the main shaft, actuating the camshaft N.

All of the above-described parts are constructed and operate as usual,are well known, and need no further detailed description.

T is the crease. My attachment, which is intended to practically fillthis crease so that no thread can fall into it, has its ends screwed att to the front of the lathe P. From these points it extends up in twovertical parts U, constructed of wire, bends into two horizontal partsU, next the floor of the crease, thence doubles back into the horizontalparts U thence up at U into the parts U and thence up into the verticalparts U which join at their upper ends, as shown. The portion U which isintegral with the rest of the device, takes the place of thefilling-grate.

It is estimated that the weaver can, when my device is employed, takeoff from five to ten per cent. more cloth in a given time, as so manystops are saved. After the device is properly placed the loom will runmore steadily, and pick-outs be prevented from occurring, theselvagewill be free from ends, and the fork Will have a better and more uniformlift.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

In combination with the lathe provided with the groove, the double-bentWire described and consisting of the end portions U, secured to thefront of the lathe, the portions U, ex-

tending rearward within the crease, the portions U extending forwardnextthe portions U, the portions U extending up vertically from theportions U the portions U extending rearward substantially horizontallyfrom the portions U and above the portions U and U, and the verticalportions U extending from the portions U and acting as a substitute forthe grate, substantially as described.
